Hypothesis
Does ghrelin play a role in the pathophysiology of obesity and eating disorders through its interaction with the corticotropin-releasing-factor system and chronic stress?
Conclusion
Ghrelin is a significant regulator of appetite and food reward, particularly in the context of chronic stress.
Supporting Evidence
- Ghrelin is implicated in food reward and can override feelings of fullness.
- Chronic stress can increase ghrelin levels, influencing eating behavior.
- Ghrelin interacts with the corticotropin-releasing-factor system, affecting energy balance.
Takeaway
Ghrelin is a hormone that makes you feel hungry and can make you want to eat even when you're not hungry, especially when you're stressed.
